Özet
During Laparoscopic surgeries, grippers are used to grasp and handle organs. Grasping joints of grippers have various toothed profiles to prevent organs from slipping. To prevent slipping, sufficient clamping force should be applied to grippers. Organ tissues may get stuck between joints and damaged. In this study, specialdesigned and pneumatic-type non-contact grippers for Laparoscopic surgeries relying on Bernoulli's principle were produced and tested for performance in terms of the maximum air speed they can reach under specific conditions. Taguchi method was used for experimental design (with Taguchi L25 orthogonal sequence) and optimization. As parameters, 5 gripper types, 5 air pressures (3-6,5 bar), 5 flow rates (2-2,8 m3/h) were chosen. Results were evaluated with signal-to-noise ratio (S/N), analysis of variance and three-dimensional graphics. A 3rd-order polynomial regression model was used for air speed, and mathematical equation was obtained. The optimum combination was of 6 bar and 2,8 m3/h flow rate. Taguchi method results with verification tests were less than the admissible 20% error value. Reliability of optimization was tested by verification experiments performed within the specified confidence interval. The results are important in terms of developing grippers working without clamping force in laparoscopic surgeries and preventing gripper-induced tissue damage.
